Verify that the device is turned on and the power cord is connected. If the device requires a power cord, make sure the power cord is plugged in. Then, check that the Thunderbolt port is thoroughly cleaned and not damaged.

Method 2. Enable Thunderbolt New Connection Configuration

This assumes that the Thunderbolt new configuration option is not enabled. In this case, the BIOS will not allow any new connections via Thunderbolt cables, as the BIOS is responsible for identifying any new devices or gadgets connected to the motherboard or PC.
